A classification system that categorizes and describes different types of design.

Interior design is a varied, robust, and diverse profession. Interior designers work across multiple markets, and many design offices or solo practitioners operate in many different types of studios, out of necessity and expertise—from large corporate offices to small practices.

Deciding which aspect of interior design to pursue comes down to experience—there are similar needs and processes of each type of interior design that overlap, both in technical requirements and programming needs that make it easy for a young designer to sample the different kinds of work environments of the profession. In addition, the strict isolation of disciplinary practices has eroded in recent years. For instance, there is an increasing use of residential typologies in commercial offices (living rooms), and the sudden need to work from home has brought external needs into the home in an unprecedented way.

Some of the many typologies of interior design practice are outlined below. Each have their own fee structures and levels of expertise. The common thread of all is a commitment to designing spaces that are accessible, accommodating, and focused on the health and welfare of their user groups.

Hospitality

Hotels, lounges, and restaurant spaces.
